    I tried the sample in book "Beginning iPhone Development", the screen becomes black after I upgrade it to universal app for both iPad/iPhone.

    What happened? do I have to modify something in source?

    Yeah, I run it in simulator3.2 and 3.1.3, both just black screen.

    But before upgraded it, the "Hello World" is displayed.

    I guess that might be about Interface Builder, because the app is ok even if I upgraded it if there are no files in Interface Builder, but all app got black screen if there are files in Interface Builder.
